There was a problem hiding this comment.
A couple of lines below, this still refers to environment variables.
Perhaps we should (for now)
- un-export
ParseKeyValueFile - have two wrappers; one variation of
ReadKVStringfor labels, and one for environment variables - those wrappers don't need the
emptyFnas an argument (while nice, we don't really need that functionality at this point)

😝 I can take care of that 👼
`--label-file` has the exact same behavior as `--env-file`, meaning any placeholder (i.e. a simple key, no `=` sign, no value), it will get the value from the environment variable. For `--label-file` it should just add an empty label. Signed-off-by: Vincent Demeester <vincent@sbr.pm>

For
--label-fileit should just add an empty label.(Same for
--label, it should never get value from the environment variables).Fix moby/moby#31087.
